WINDING- MECHANISM.

T0 all whom 'it may concern Be it known that l, CHARLES B. WEBSTER, a citizen of the United States, and resident of Fall River, in the county of Bristol and State of Massachusetts, have invented an improvement in lVinding Mechanism, of which the following description, in connectien with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to winding mecha- .nism for forming yarn. or thread packages and specifically and more particularly to builder mechanism for ring spinning or twisting mechanism.

The present invention is intended to present a simple form of single acting traverse and gain controlling mechanism, to which eX' sting mechanisms may be readily adapted and in the illustrated embodiment l have shown the same as involving the take-up of the flexible element although, obviously, by a suitable re-arrangement of parts the mechanism is equally well adapted to the letoi'l' of the flexible element.

ln order that the principle of the invention may readily be understood, l have chosen to illustrate that embodiment thereof` consisting of builder mechanism for ring spinning frames,-that is, a specific application of winding mechanism.

ln the drawings: Figure l is a front elevation of one form of builder mechanism for ring spinning frames constituting an embodiment of the invention; Fig. 2 is a View of said mechanism partially in vertical transverse section and partially in end elevation; Fig. 3 is a view in side elevation of a portion of the mechanism shown in Fig. l, upon an enlarged scale; Fig. '-l is a detail, partially in section and partially in side ele- `ration of a portion of the mechanism shown in Fig. 3; Fig. 5 is a detail in side elevation of one of the series of interchangeable sheaves; 6 is a longitudinal section taken upon the line G-G of Fig. 3; Fig. 7 is a longitudinal vertical section taken through one of the shafts of the mechanism; and Fig. 8 is a detail showing the preferred manner of detaehably supporting the sheaves in position.

In yarn or thread winding mechanism to which my invention relates, the coils of yarn are laid along the yarn receiver by eecting a relatively oscillatory movement of a yarn guide and the yarn receiver along the latter for a portion of its length, which movement is generally called the traverse,; and the package is built by shifting theppath of this relative movement progressively along the aXis of the yarn receiver, which shifting is usually termed the gain. ln the formation of such a yarn package, a maximum diameter is reached at a point above the lower endl thereof due to the cooperative effeet of the traverse and the gain; and the portion of a package from its lower end to such point of maximum diameter is termed the base while the conical form resultingat the other end of the yarn` package is termed the chase, or the taper and its terminus is the nose of the cop.

My invention provides means whereby the package may be wound or formed with elficiency in a winding or spinning or twisting machine; and particularly in a spinning or twisting machine it furnishes means whereby the tension of the yarnnin winding may be well controlled and the lay of the yarn thereby benefited.

ln the formation of the base of the package, the invention provides means whereby the successive layers of yarns may be so laid, one over the other, until the full diameter of the package is secured, that each bottom coil of each layer is laid safely up and above the bottom coil of the preceding layer, (assuming the yarn receiver to be upright and the yarn to be wound thereon from the bottom upward, as in the preferred arrangement of parts of mechanism embodying my invention) and while the mechanism accomplishes this broadly in the formation of the base of a package, it may be yarranged to continue the'same winding effect throughout the entire length of the package. This feature of the winding is accomplished by providing a gain which may be of any suitable character and which preferably increases, progressively or otherwise, throughout the whole of the base of the package at least. Throughout the reto the axis ofthe package. By this means,

mainder of the package, the gain should be such as to maintain the body of the package substantially uniform in diameter. To this end I may, While constantly increasing the traverse be maintained. Coperatively with this mechanism for increasing the gain, mechanism is provided to increase the traverse throughout the formation of the base and preferably throughout the formation of thewhole package.V The result of this increase of traverse is obviously'tov lay each successive layer of yarn over a slightly greater extent axially of the package; and further, due to the constant speed of the spindle or other yarn receiver, and in ring frames particularly, due further to the constant speed ofthe feed rolls, if each traverse is edected in the same period of time (which is accomplished by giving the primary controller of the traverse movement a stroke constant in time and distance), the Ayarn will each time be laid in coils a little more .videlyrseparated. Having reference to the utiliza-tion of such a yarn package which involves its unwinding features, the result is that the increasing traverse Vfrom base to nose gives a reversely decreasing taper from nose to base, so thatthe yarn withdrawn by draft axially of the package is drawn from a surface on the package approaching more Y and more nearly toa surface at right angles as the length of yarn extending from the surface wherefrom it is being delivered to the point above the package where draft is being applied to the yarntends to increase, and ballooning of the yarn away from the package tends to increase, this tendency to increase the ballooning eHect is checked by the yarn drawing from a surface tending to approach more and more nearly to a flat surface at right angles to the package; and

when the yarn package is positioned in the L shuttlethis described construction of packagechecks the tendency of the yarn to balloon out and contact with vthe sides of the shuttle and therefore, tends to decrease breakage. Furthermore, asy the base of the cop is reached in the unwindingl and throughout the whole package, if and when the increasein' gain is established through the whole package) each bottom coil of each layer (having been safely laid by means of the increase in gain over and above the bottom coil of the preceding layer) is permitted to be withdrawn without foulingr with and tending toV slough oif the preceding layer. These advantages thus secured in they unwinding are of great practical importance in Weaving Where the yarn is subjected to quick intermittent draft reaching a speed of from five to ten yards a second.

A yarn spinning frame constructed in accordance with my invention is provided with a ring rail and continuously rotating yarn receivers, herein represented as spinning spindles having bobbins of paper or similar tubes thereon. l/Vithin the scope of my invention, the yarn may obviously be 'spun or wound upon the bare spindles. The

travelers or the rings and the travelers constitute the yarn guiding means and the ring rail or the ring rail and poker constitute a yarn guiding holding means, and I cause a relative to and fro traversing movement between said yarn guiding means and said yarn receivers. Preferably this is effected by imparting the described traversing movement to the ring rail.

Inasmuch as each traverse is increased over its predecessor, each traverse advances more at the top of the wind than at the bottom thereof. The effect of the described traverse and gain are to build a yarn package which at the vbottom extends from the surface of the receiver to a maximum diameter without laying the bottom coil of any y"ind or traverse on top of or below the bottom coil of the preceding layer or travincrease in the gain throughout at least the base of the package, together with the directy increase of the traverse, lays the yarn so uniformly that the chase of the yarn package is formed with astraight line constituting a conical bottom in vertical cross section, until the maximum diameter of the cop or other yarn package is reached. Thus, the increase in traverse and incremental increase in gain are effective to produce and maintain a correct and advantageous form of package. Vlllhilel have referred to the increase in the traverse as constant, this term is employed generically or broadly to refer to a preferably regular increase in the traverse, such increase occurring at a certaui part of the traverse, or if desired, at a certain part of each of a series of traverses. I preferably impart the increase to the traverse and the increase to the gain during the up-stroke of the ring rail, and preferably -near the end of such v11p-stroke and terminating with the end of the up-stroke.

Inasmuch as the builder cam employed in the disclosed embodiment of the invention rotates preferably at a constant speed, and inasmuch as the traverse is regularly increased, it follows that the speed of the ring rail is correspondingly increased, and inasmuch as the addition to the traverse and the addition to the gain are imparted in Ythe present-embodiment at or nearl the end of the up-stroke of the ring rail, it follows that the speed of the movement of the ring rail is accelerated each time toward the end of 1ts up-stroke,-that is, when the yarn 1s winding upon the nose of the yarn package.

An important object of my invention is the provision of suitable means whereby the traverse and also the gain may be changed independently of each other, and whereby if either the traverse or the gain be varied, suitable compensation may be made to prevent variation of the other factor, if desired. ln this manner, bobbins may be wound which are of different lengths, but wherein the traverse is correspondingly the same, and wherein the total gain varies. Any other desired cha-nge in the factors entering into the winding of the bobbin may be made.

Referring more particularly to the drawings, the builder element herein shown is a cam, as indicated at 2 in Fig. 1, it being fast upon a shaft 1, supported upon the framing and driven preferably at a constant speed in the direction of the arrow thereon, from any suitable mechanism, such for example as a worm shaft which is itself driven by sprocket gearing or otherwise, from the main drive shaft of the spinning frame. l am enabled, because of my invention, to drive the shaft 1 and its cam 2 at a higher rate of speed than heretofore without changing the speed at which the drawing or feed rolls or spindles are driven, and therefore to impart more rapid traverses to the ring rail without, however, changing the speed of the spindles which are preferably driven by bands from the drum, and hence independently of the ring rail. Y

`While 1 may employ any suitable contour or type of builder element, 1 have herein represented the builder cam as adapted to make but a partial revolution for each complete traverse of the ring rail.

rlhe spindle rail is represented at 3, the' spindles at 1, the ring rail at 5, the spinning rings at 6, and the box rail or frame of the spinning frame at 7. These parts may be and preferably are of usual formation and construction, the spindles being continuously rotated in one direction, preferably by bands from the usual drum and the yarn being delivered thereto by the usual sets of drawing rolls, not shown.

duitably mounted in the frame of the machine, upon a stud or pivot 8 is a builder lever 9 preferably having a member 10 relatively adjustable with respect thereto by a set screw or otherwise, as indicated at 11, and having a roll 12 engaging the periphery of the builder element 2. It will be observed that the builder lever 9-10 is mounted .to rock in a plane extending longitudinally of the frame, and this construction is preferably employed wherein the parts operate by take-up of the flexible element. I may, however, employ a lever mounted to swing in a plane transverse to the frame, and particularly if the parts operate by let-off of the flexible element as maybe readily effected within the scope and ob] ect of my invention.

Suitably mounted in the frame of the machine and as herein shown, in a bracket 1 is a bell crank lever lll having an arm 15 upon which rides the lower end of the poker arm or rod 16 depending from the ring rail 5. The lever 111 is provided with an Iupward extension 17 to the other end of which is suitably secured one end of a flexible connection herein shown as consisting of a pair of chains 18. These chains are arranged in pairs throughout the frame and a suitable number of sprocket chains and bell crank levers and poker arms or rods are provided to impart a steady up and down movement to the ring rail 5, and preferably a. ring rail and a row of spindles are arranged at each side of the spinning frame.

1n building the yarn package, the yarn is laid upon the receiver in a series of nested cones, each of which is formed during a Jtraverse of the ring rail. In order that these traverses may extend along or with suitable relation to the receiver, an incremental gain of any suitable character is imparted to the traversing mechanism preferably between the successive traverses throughout atleast the base of the package, during the winding of which the gain is preferably a progressively increasing one. In the present embodiment of the invention, both the traverse and the gain are elfected'through the chain or other flexible connection or connections 1S. Herein, each chain 18 is representedas attached iixedly at one end to the arm 17 of the lever 11 and at the other end is connected as hereinafter described to a governing device carried by the builder lever 9-10. The longitudinal pull imparted to the chain or chains 18 by the builder element 2 rocks the bell crank lever 14 through arcs, the angular extent and position whereof are modified, as hereinafter set forth, by mechanism acting upon said chains 18 between the ends thereof, to effect the laying of the yarn by traverses which are maintained undiminished and preferably have a regular uniform increase and by a gain which is also maintained undiminished and which preferably progressively increases throughout at least the base of the package. y

In order to secure a traverse and a gain of the character above indicated and which may be varied as desired, 1 have provided adjunctive means coperating with the builder lever and connections therefrom such that the invention may be readily applied to existing types of ring spinning frames, (inasmuch as an important object of the invention is to provide mechanism of indicated most clearly in Fig. 2, and uponk the upper end thereof have mounted upon a pivot or stud 2O a lever 21 having at its lower end a toothed segment 22 meshing with a gear 23 having a hub 20 loose upon the shaft 24, that is mounted in an upward extension 25 of the builder lever 9-10.

As shown most clearly in F ig. 7 the gear 23 is provided with a hub 26v extending through the bracket 19 (which is suitably recessed to permit the described rocking of the builder lever 9-10 and the parts car'- ried thereby), and fast upon said hub` 26 is a disk 27 carrying a pawl 28 adapted to engage the teeth of a ratchet 29 shown most clearly in Fig. 3 and which is fixed upon the shaft 24. The said ratchet 29 is adapted, vfhen intermittently actuatedV by the pawl 28, to impart a step by step rotation to the shaft 24. The upward extensionV 25 is proyf vided with a sleeve 30 wherein the shaft 24 is mountedrand upon the end of the sleeve `30 adjacent the disk 27 is mounted a casing 31 partially surrounding the ratchet 29, as indicated in Fig. 3, and providing means whereby the pawl 28 engages the ratchet at or near the end of each movement or oscillation of the segment 22. rIhe casing 31 is provided with a hub 32 which is fitted on to the sleeve 30 and provided with va set screw 33 for securing it thereon in fixed position, but permitting circumferential adjustment of the shield, thereby to vary the extent of the pick. It will be observed that with the pick mechanism as above shown, a pick takes place when the ring rail is completing the up portion of its traverse although within the scope of the invention the pick may take place while the ring rail is completing the last portion of its down traverse or at such other time yas may be suitable.

Since the'pick mechanism in the present embodiment ofthe invention effects both traverse and gain it results that not only is the incremental increase in gain, of whatever character, added just at the time when the ring rail is completing the up portion of its traverse, but also, since the increase in the traverse increases the general speed of the ring Vrail yduring the traverse, it follows that the traverse lis speeded up just as the ring rail is completing its up-stroke. `These two factors coperate in the operation of the mechanism to secure the proper laying A of the yarn by tending, first, to keep the coils of each traverse laid well Yabove each other at the top, and second, to reduce the number of coils laid at the top,-that is,

kerse not only tends to compensate for the inherent tendency of the spinning mechanism to Vlay more winds of yarn Vat the upper portion of its traverse, but it also tends to compensate for the lag of the traveler at the upper portion of the upstroke of the Vring rail and Ytherefore results in less variation ofthe speed of the traveler due to this lag at the up portion of its stroke; and not only tends to reduce causes'effecting the yarnV breakage but tends to produce a' yarnjpackage wound with more uniform tension throughout.

The lever 21 carrying segment 22 may be oscillated in any suitable manner, but preferably by movement of the builder lever 9-10. Herein for the purpose, I have provided'the builder lever with the arm 25 as hereinbefore described (or I may mount such arm upon the rock shaft 8 co-axially with the builder lever 9-10). 'At its upper end the arm 25 is provided with a lateral extension 34 having a transverse slot 35. The lever 21 extends upwardly beyondV its pivot 20 as indicated in Figs. 2 and 3, and is there provided with anopen slot 36 receiving a bolt 37 extending through the lever 21 and the slotted extension V34. The

provision of the transverse slot 35 permits variation 'in the relation of the 'segment 22 and the gear 23.

Vertically mounted in the arm 25 is a threaded shaft or screw 38 shown most clearly inrFig.k 4 and fast upon the lowerV end thereof is a beveled gear 39 meshing with the beveled Oear 40 that is fast upon the shaft 24. The shaft or screw 38is readily removable and may be replaced by one having a coarser or a finer thread, in lieu of varying the pick. In either manner the traverse maybe varied but preferably I accomplish this result by varying the pick.V

Held from turning upon Vthe screw 38 is a nut 41 which at the commencement of the building yof the cop is at or near the lower end of the screw 38 and is gradually elevated by the rotation of the screw from the shaft 24.

The nut 41 has loosely mounted therein the stud shaft 42 extending through and projecting at both sides from said nut.l VKeyed at 42 upon the ends of the said stud Y shaft 42 so as to be readily and independently removable are two sheaves 43-44 shown most clearly in Fig. 2. These sheaves are herein represented as truly circular but may be formed as scroll cams, or of any other desired form to effect the take-on or let-off of the chain in anydesired manner.

The ends of the flexible elements or chains 18 are fixedly attached to the periphery of the said sheaves by bolts or otherwise as indicated at 45 in Figs. 1 and 3.

The sheaves 43-44 may be secured to the stud shaft 42 in any suitable manner permitting ready removal thereof so that other sheaves of greater or less diameter may be substituted therefor. Within the scope of my invention, I may provide a series of expansible sheaves or like devices so that the diameter thereof may be increased or diminished and also within the scope of my invention I may provide the shaft 42 with an additional set or sets of sheaves so that the chains may be shifted from the sheaves of one set to those of another of different diameter upon suitable change in the position of the parts. Thus, in any suitable way I provide for varying the effective diameter of the sheaves. The described result is most simply secured by providing a series of interchangeable sheaves of different diameters, any desired number of which may be employed. f

As heretofore pointed out, by changing the pick (that is, by varyingthe number of teeth by which the ratchet 29 is advanced at each pick) or by changing the pitch of the screw 38, I change the traverse, inasmuch as the traverse is determined by the total outward movement of the builder nut 41. The length of the bobbin or yarn package represents the total gain and it is, therefore, evident that if the pick be lessened., thereby lessening the traverse, and there is no compensating change governing or compensatingly increasing the gain, too short a bobbin or yarn package would be secured. Inasmuch as the outward movement of the nut, (which is controlled by the pick) represents and effects thetraverse, and inas much as rotation of the sheaves 43-44 rep resents and effects the gain, I therefore provide means, of which I have disclosed one embodiment, whereby I may ychange the traverse, and may, if desired, compensatingly change the gain. If no provisions existed for compensatingly changing the gain upon variation of the traverse, then a change in the traverse would necessarily modify the gain, so that in many cases the result would be too short a yarn package. In accordance with my invention, however, I may change either the traverse or the gain independently of each other. If, therefore, I wish to change one of the factors, as for example the traverse, without changingV the other factor, as for example the gain, then after changing the traverse I make a change in the gain to compensate for the change in the traverse, so that the resulting gain'is the same as it would have been had the traverse not been altered. Furthermore, within the scope of my invention, I may change both the traverse and the gain either compensatingly or otherwise and within the scope of my invention the gain may be of' any suitable character. If, for example, the sheaves 43-44 be formed as scrolls, then a progressively increasing gain results. It will thus be evident that with the same outward movement of the builder nut I may take on (or let off) less chain by making the sheaves 43-44 smaller or by making larger the remaining sheave of the series to be described. Conversely, if, with the same total outward movement of the builder nut, I wish to take on (or let off) more chain, then I employ larger' sheaves 43-44 or a smaller final sheave of the series. Furthermore, within the scope of my invention, in different total movements of the builder nut 41 I may take on (or let o) a fixed amount of the chains 18.v Thus I have provided means whereby in ldifferent cases, more or less increase in the traverse may be had as desired, with any desired let-off or take-on of the flexible elements 18. To this end I have, in Fig. 5, shown one of a pair of sheaves 4Gk which is of a slightly larger diameter than the sheaves 43-44. When a pair of sheaves 46 is substituted for the sheaves 43-44, it is evident that a greater amount of chain is taken on with the same total movement of the builder nut. It is also evident that if the mechanism be employed to let off the fiexible element or elements instead ofr to take on the same, that the sheaves 46 will in such case let off a greater amount thereof forl the same total movement of the builder nut. If it be desired to operate by let-off', I may, as previously stated at the outset of the specification, effect this by a suitable rearrangement of the parts. Referring to the illustrated form of the invention, if it be desired to operateby let-off, the chain v18 may extend directly to the under side of the sheaves 43, 44 and be suitably connected to said sheaves instead of extending to the upper side thereof, as herein shownawherein mechanism operating by take-up 1s illus-- trated. It is, therefore, evident that by the described mechanism I have provided means whereby, if desired, the amount of increase in the traverse may be varied. It is evident that other suitable mechanism may be provided for the same purpose. .I have also provided suitable means for vary-- ing the `increment of gain and for varying the total gain, such means for varying the increment of gain being independent of the means for varying ythe amount of increase in the tra-verse. V 'f As shown most clearly in Figs. 2, 3 and 8 I also key at 42 upon the stud shaft 42, and in this instance adjacent the sheave 44, a sheave 47 of suitable diameter and having secured to the periphery thereofy at a suitable point, as by means of a bolt, a flexible element'or chain 48, the other end whereof is fixedly secured at 49 to the builderV lever on to the sheaves 48-44y than would be the case if the sheave 47 were of relatively smaller diameter. The chain 48, connected as it is to the sheave 47, Aand to the builder lever 9-10, 'compels a slow rotation of the sheaves 43-44 in the direction of the Varrow in Figs. 8 and 4 during the outward travel of the nut 41 'from the,` fulcrum of the builder lever 9-10.y The sheave 47 may be of any suitable diameter and as stated, mayv be varied as desiredby the provision of interchangeable sheaves or in any other manner referred to in connection with the sheaves48-44, so that any desired character of gain in the yarnpackage may be secured. Preferably the character of the sheaves is such'that throughoutat least the'base of the yarn package a progressively increasing gain is imparted though, as previously stated, within the scope of my invention, any other Vdesired character of lgain may be imparted as for example, a progressively decreasing or other decreasing character of gain.y Preferably, however, the construction is such las to maintain the gain undiminished throughout at least the winding of the base of the package. If it be desired, as already discussed, to operate the mechanism by let-olf, in which case the chainsr18 may, as previously stated, extend directly-to the under side of the sheaves 43, 44, the chain 48 should also be reversed orirearranged, and may extend from the under side of the sheave 47 to a suitable point of attachment upon the upright arm of the builder lever above said sheaves. In other forms of builder arms or levers, suitable rearrangement may be made to effect change from take-up to let-oif,`or vice versa. AThe gradual elevation of the nut 37=and the consequent change in position of the chains 18 effect a constant increase infthe traverse. Asherein represented, the pick mechanism is con- Stant or unvarying Vin operation andthe movements'of the nut 41 upon the Lscrew 38 are uniform.

The described movements of the parts are such as to effect an increase in the gain throughout at'leastthe base of the package and it will be observed that the vdistance between the point of attachment of the chains 1 8 to the arm 17 of the bell crank lever and the sheaves 48-44, "measured along the shortest line, is incrementally lessened. ,Moreoven inasmuch as when the ring rail 5,is in its lowermost position, Vthe arm 15 of the bell crank lever is somewhat` below and is moving toward the horizontal., it follows that the linear movements impartedk by lthe arm 15 to the poker arm orrod 16, gradually increase in length due tov the movement cfs-aid arm upwardly toward the horizontal in analogy to the increased linear movements imparted by a crank when approaching the horizontal. Such increased linear movements ofthe poker arm or rod 16 continue throughout the formation of the base of the package, at least.

In the present embodiment of the invention the elements combine to-effect an increasing gain throughout the formation of the base of the package and the continued movement of .the arm 15 lis not 'thereafter such as substantially to modify4 lthe character of the gain'during the further formation of the yarn package.

It will be evident from Vthe foregoing that the invention is readily adapted for usc in connection with mechanism operating either vby take-up or by let-olf of the flexible element, it being herein shown as'operating by take-up. Any desired Vtotal increase of traverse can be had, aspreviously stated, by properly tregulating the pick Vmechanism and the screw 38 controlling the builder nut. Vf ith any total increase ofk traverse, any desired total increase of gain can be had. Thus anincreaseV of total traverse can be had in the same movement of the builder 43, 44, to which the chains 18 are connected, or by decreasing the diameter of the disk 47 to which the chain 48 is attached. Conversely a decrease of total gain can be had by decreasing the diameter of the disks 43, 44, or byjincreasing the diameter of the disk 47. Finally the rate of variation of the gain can be controlled byproperly varying theform ofthe disks 48, 44, and if dcsired of disk 47, vas by making them of scroll form, asl hereinbefore set forth. 1t will thus be seenthat the mechanism has a maximum capacity for adjustment. It is thus vpossible to change thetotal length of the cop or yarn'package and a given amount of increase ofthe traverse can be'retained, as also any desired variation of the gain.

Although I have referred to the increase in the traverse as constant, it will be understood thereby is meant a regular or periodicy increase inasmuch as in practice the traverse is not increased at all instants of time during the operation of the mechanism, but preferably at a certain period of time 0r part of each traverse.

After the nut al has been elevated by rotation of the screwY 38 in the building of the yarn package, the said nut is returned, preferably by hand, for the formation of the next set of yarn packages. Herein for the purpose, I have provided the shaft 24 with a. crank handle 50 shown in Figs. l and 8, so that by rotation of said shaft and of the screw 38, the nut il may be lowered to the desired extent.

It will be understood from the foregoing description that the effect of the travel of the nut 41 upon the chains 18 is such that the arcs of movement of the bell crank lever l-lnot only gradually increase in length, providing the gradually increasing length of conical layers, but the said arcs of movement are gradually increased contra-clockwise so that the rods or poker arms 16 descend to an incrementally higher point after each upward operation of the traverse, thus providing a gain which, as previously stated, is increased.

In employing` the term traverse I mean a complete forward and return movement of the yarn guide or complete relative forward and return movement of the same with respect to the yarn receiver. Each return movement of the traverse terminates at a distance above the commencement of the traverse measured by the extent of the gain.

As previously stated, the disclosed embodiment of the invention provides means for controlling the gain and traverse in a form wherein the flexible element is progressively shortened or taken on. Modification of the mechanism to give the same control, 'a'. c., increasing traverse as discussed, and generally decreasing gain as discussed is readily secured by so arranging the outwardly moving builder nut and scroll that the flexible element is released by increasing incrementsI as the builder nut moves outward by uniform increments; being essentially the reverse of the arrangement herein shown. Furthermore the application of the said traverse and gain controlling mechanism to builder mechanism wherein the iiexible element is let off or elongated during the winding operation, will be readily apparent to those skilled in the art. rlhus, either a take-on or let-ofi' form of mechanism may be provided.

another advantage of the described wind is that l so regulate the decrease in the speed in the winding on of the yarnA upon the portion of the yarn receiver that is of least diameter (and by such diameter l mean the least diameter of that portion of the yarn receiver covered by each traverse of the yarn) that the lag of the traveler as the ring rail moves toward and away from the ends of the yarn package is minimized. Therefore, a more generally rapid movement of the ring rail per minute may be edected, so that with an assumed spindle speed and an assumed ring rail speed, a more open lay of the wind may be accomplished. I have previously stated that the lag of the traveler is diminished by increasing the ring rail speed inasmuch as fewer turns of the yarn are laid at the upper end of each traverse. It will be evident that by laying the yarn as an open wind, the number of turns is further lessened, thus still further minimizing the lag of the traveler.

As a specific instance of the capacity of the described mechanism, l may'state that it is possible to get an increase in the traverse from a starting traverse of say three quarters of an inch to an ending traverse of one and one eighth inches and simultaneously to take on live inches of the chains 18. vlt may, however, be desired to get an increase in the traverse from a starting traverse of three quarters of an inch to an ending traverse of one and one half inches and at the same time not take on more than the Vsaid five inches of chain. Any other suitable manipulation may be effected. lt will, therefore, be understood that by avoiding the taking on of a greater amount of chain, I avoid the lifting of the ring rail too high and the winding of a too long bobbin.

Having thus described one illustrative embodiment of my invention, l. desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being Set forth in the following claims.
